Check Point security advisory (AV26-902)

Canada's Cyber Centre issued advisory AV26-902 warning of two Check Point RCE flaws, including VPN authentication bypass CVE-2026-85102.

The Canadian Centre for Cyber Security released advisory AV26-902 on September 9, 2026, covering vulnerabilities in Check Point Security Gateway, Spark Firewall with Site-to-Site or Remote Access VPN, and Security Management Server across multiple versions. CVE-2026-85102 is an authentication bypass and remote code execution flaw in Remote Access and Site-to-Site VPN, while CVE-2026-85103 is an ASN.1 decoding heap overflow enabling remote code execution. Administrators are urged to review the linked advisories and apply updates as they become available.

Check Point Patches Critical VPN Vulnerabilities

Check Point patches two critical unauthenticated RCE flaws (CVE-2026-85102, CVE-2026-85103) in VPN gateways and firewalls; no exploitation observed.

Check Point released patches for CVE-2026-85102 and CVE-2026-85103, two critical vulnerabilities (CVSS 9.8) enabling unauthenticated remote code execution in products using VPN functionality. CVE-2026-85102 involves improper validation of certificate data during VPN negotiation, while CVE-2026-85103 is a heap overflow in the VPN certificate ASN.1 decoding flow. Updates cover versions R82.10, R82, and R81.20; manually defining VPN rules is offered as a mitigation, though it does not apply to locally managed Spark Firewall instances. Check Point discovered both flaws internally and reports no evidence of exploitation in the wild.

NCSC Warns of Critical Check Point VPN Flaws as Large-Scale Exploitation Is Expected

Dutch NCSC warns of two critical CVSS 9.8 Check Point VPN flaws enabling unauthenticated remote code execution, urging immediate patching before mass exploitation.

The Dutch NCSC warned that CVE-2026-85102 and CVE-2026-85103, both rated 9.8 CVSS, allow unauthenticated remote attackers to execute arbitrary code on Check Point Quantum Security Gateway, Spark Firewall, and Security Management Server deployments when VPN is enabled. CVE-2026-85102 stems from improper certificate trust validation during VPN negotiation, while CVE-2026-85103 is a heap-based buffer overflow in ASN.1 certificate decoding. Check Point shipped emergency updates on September 9, 2026, including R82.10 Take 44, R82 Take 126, and R81.20 Take 166 or later, plus LivePatch for eligible systems. No public exploit code exists yet, but the NCSC rates exploitation likelihood high and recommends restricting UDP ports 500 and 4500 to known peers as a stopgap.

2026-012: Critical Vulnerabilities in Check Point Products

Check Point issued emergency hotfixes for two CVSS 9.8 flaws (CVE-2026-85102, CVE-2026-85103) enabling unauthenticated RCE on VPN-enabled gateways.

On 9 September 2026, Check Point released emergency security updates for CVE-2026-85102 (improper certificate-data validation in VPN negotiation) and CVE-2026-85103 (heap overflow in VPN certificate ASN.1 decoding), both CVSS 9.8, allowing unauthenticated remote code execution. The flaws affect Security Gateway, Security Management Server, and Spark Firewall deployments configured with Remote Access or Site-to-Site VPN, spanning versions R80 through R82.10. CERT-EU advisory 2026-012 urges immediate hotfix application, prioritizing internet-facing and perimeter appliances.

Check Point Discloses Two 9.8-Rated VPN Certificate Flaws Enabling Unauthenticated RCE

Check Point patched two 9.8-rated VPN certificate flaws, CVE-2026-85102 and CVE-2026-85103, enabling unauthenticated remote code execution; no exploitation observed yet.

Check Point disclosed and began patching two critical (CVSS 9.8) vulnerabilities in VPN certificate handling on September 9: CVE-2026-85102, a certificate trust validation failure in VPN negotiation on Security Gateways, and CVE-2026-85103, a heap-based buffer overflow in ASN.1 decoding affecting Quantum Security Gateways and Security Management Server. Affected branches include R81.20, R82, and R82.10 Jumbo Hotfix levels; fixes ship via Live Patch or the latest Jumbo Hotfix. The company found both internally and reports no evidence of exploitation; the Canadian Centre for Cyber Security also published an advisory listing Spark firewalls.

Critical Check Point VPN Vulnerabilities Enable Remote Code Execution Attacks

Check Point patched two critical VPN flaws, CVE-2026-85102 and CVE-2026-85103 (CVSS 9.8), allowing unauthenticated RCE on Security Gateways.

Check Point disclosed and patched two critical VPN vulnerabilities, CVE-2026-85102 (improper certificate trust validation, CWE-295) and CVE-2026-85103 (heap-based buffer overflow in ASN.1 certificate parsing, CWE-122), both rated CVSS 9.8 and exploitable for unauthenticated remote code execution under specific conditions. The flaws affect Security Gateway, Security Management Server, and Spark Firewall deployments on R81.20, R82, and R82.10 branches plus end-of-support versions such as R80.40 and R81, while R82.20 is not affected. Check Point reports no evidence of active exploitation or public PoC; Live Patch rollout began September 9, 2026, and administrators without it must install Jumbo Hotfix Accumulator builds (R82.10 Take 44+, R82 Take 126+, R81.20 Take 166+). For Site-to-Site VPN, restricting UDP ports 500 and 4500 to known peers serves as an interim workaround, but no mitigation exists for Remote Access VPN or Spark Firewalls.
